Surefly SIM4P 4-CYLINDER Impulse Coupled MAG Replacement

Now approved for the replacement of both mechanical magnetos on most certified four- and six-cylinder Lycoming and Continental powered aircraft with dual SureFly Electonic Ignitions. Please review the Engine and Airframe STC's and installation instructions for further application information.

Note: Surefly strongly recommends the customer purchase a NEW slick-style harness and fresh spark plug set with every SureFly SIM.

The vast majority of 4-Cylinder applications will replace the impulse coupled magneto. 4.4 lbs.

SureFly is an FAA certified electronic (solid state) magneto replacement. The SureFly Ignition Module replaces one magneto - generally the left or impulse-coupled/starting magneto on most aircraft. 4 and 6-Cylinder models are available for Lycoming and Continental engines.

Replacing just one magneto eliminates magneto maintenance and cuts associated costs in half! Zero maintenance. Zero rebuilds. Zero overhauls. Most fixed-wing single engine aircraft can enable SureFly's advanced timing feature for improved cruise flight efficiency. Many other aircraft will be able to use the advanced timing feature as the FAA extends SureFly's Airframe STC AML.
